I'm building a loft bed for a queen size bed. I planned to build a platform and support it with 4x4s, but I'm having trouble finding untreated 4x4s. I plan to loft the bed 5' or so. The platform will be made of 2x6's covered in 1/2" plywood.
This shows what I'm planning to do:
Can I use two 2x4s instead of the 4x4's to carry the load?
If so, will nailing/screwing them together in several places be sufficient to hold them together?
I'd like to use 3/8" bolts to join the platform to the posts (for easy disassembly). If so, should I only bolt down the long side of the platform, or try to place bolts on both sides of the corner? If the latter, how should I put a bolt through the narrow side of the joined boards?
